Beyond Lichdom

Many servants of death view lichdom as the ultimate state of power and immortality. Yet the ultimate does not always mean the end. The oldest liches discover that although the transformation into undeath spares them a physical death, it does not make their forms immune to the ravages of time. While many go to great lengths to preserve their corpses, some liches facing bodily dissolution make a second foul apotheosis—their evil spirits possess their own crumbling skulls and augment them with gems enhanced with soul-binding necromantic magic, thus transforming themselves into legendary abominations known as demiliches.
